To all whom it may concern:

Be it known that L DUDLEY T. FISHER, a citizen of the United States,residing at Columbus, in the county ofFranklin and State of Ohio, haveinvented certain new and-useful Improvements in Cable-Reelsfor HaulageMechanism, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This inventlon relates to improvements in draft or haulage mechanism forelectriclo comotives of the sort employedfor pulllng from one point toanother cars which'are not provided with their own engines ormotors. Forexample, in coal mines relatively small cars are used which, while beingloaded are separated from each "other and" scat tered over more or lessof the mine, one in oneroom or at one loading point andothcrs at others.The older plan, where animal power was used, was to hauleach of thesecars singly by an animal from the room, after it had been loaded, to acollecting point where a number of the cars were coupled together toform a train ory tripi Since the introduction of electric power use hasbeen made for this purpose of gathering locomotives, each having a reelwith an electric cable thereon, the terminal of which can be connectedelectrically to a currentsupplying wire, so that as the car moves awayfrom the source of supply, the cable on the reel will maintain acontinuity of electric conductors to the motor. In using this apparatus,the locomotive is itself run into the rooms successively and coupled tothe isolated loaded cars and thereafter hauls these to the gatheringpoint. Under many circumstances these gathering locomotlves with cablereels cannotjbe used to advan tage, particularly where the mine roof is;

fastened by a key 4 to this base in such a way that it is held firmlyagainst rotation.

low or wherethe track has been hastily constructed, as the branch tracksfrequently are which extend from the entry into the room.

The present invention relates to an apparatus adapted to be attached toan ordinary locomotive and of such nature that the locomotive can remainin the, entry or at some distant point and yet the loaded car can behauled by power toward it while it remains stationary.

The object of the invention is to provide improved structural featuresand an improved arrangement of parts. I V

A further object is to provide improved friction lining 5 betweenyit andthis resting upon the base 3.

Fig.8 is a view showing the reel and a its power transmitting devices, invertical central section and showing an electric motor partly inoutlineand partly in section. Fig, 41s a side'elevation of the motor'andreel. Fig. 5 is a horizontal section on the line n w, Fig. 3. i

A indicates a car, an electric locomotive of the kind used in coal minesbeing selected for thepurpose of illustration Its wheels Bare fitted tothe'track railsi Its body is formed of a heavy cast frame having theside parts C, C and the end connecting parts D, D. Many of the parts ofthe car or 1000- [motive are indicated conventionally by dotted lines.At E the electric motor is situatedin the spacebetween the twoaxles b, bThis motor is geared toone of the axles in any suitable way, and bypreference the aXles are geared together or connected by chains andsprockets. At F there is a chamber orspace left for the motorman and forthe parts which he is called upon to manipulate frequently, such as thewheel of the controller at G and the hand wheel of the brake mechanismat At the end ofthe locomotive opposite to that where the motorman isplaced I arrange a reel forthe haulage cable. This is indicated by 1 andismounted on a vertically arranged shaft 2. This shaft is secured to abase 3 which is in the form of a strong barextending across from one ofthe side elements C of the car body to the other, and firmly boltedthereto. The shaft 2 is The reel 1 can rotate loosely and freely aroundthis shaft when it is disengaged from theother parts. The reel has anantithe shaft 2,

16 indicates a hublike part for the reel or sleeve is secured, or withit is formed a gear wheel9.- e a a p 11 is a spur gear wheel mountedloosely on the shaft2 above the reel hub. This gear wheel ll is of aslightly larger diameter than the wheel 9, and has one more tooth, for apurpose to be described. With this wheel are combined devices forlooking it to the shaft 2 and holding it stationary. To accomplish thisthe wheel itself may be provided with a clutch-element, preferably byformingjaws or teeth 24L upon its upper side. With this clutch-element amow able element such as a pin or cross-bar 18 can engage, it extendingthrough slots 19 in the shaft ;2 and being. movable into and out ofengagement with the jaws or teeth 24:. To so move it,.use ismade'of therod 21 connected to the clutch pin 18 and extending downward through theshaft 2. At the lower end the rod is connected to a belllever 22 fromwhich there extends an operating rod 23 to the motormans end of the car.

i The shaft 2, at its upper end, supports the field frame 25 of themotor 8. The armature 26 is supported by the collar 6 on the shaft 2 andrevolves freely on suitable antifriction bearings.

15 is a sleeve or cylinder secured to the under-side of the armature-andextending downward therefrom. From the cylinder there extend stillfarther downward arms 27, which, at their lower ends carry a ring 28concentric with the shaft 2. This ring is formed with a number ofbearings 29 andin each of these is mounted a shaft 12.

7 Each shaft 12 carries two pinions 13 and 1 1.

These pinio-ns differ slightly in size, the upper one having the smallerdiameter, but have the same number of teeth. The pin 1. ions 13 meshwith the wheel 11, and those at 14 mesh'with the wheel 9. When the armature is revolved the pinion shafts 12 are rotated bodily around theshaft 2 and if the wheel 11 is stationary, that is, locked to the shaft2, it will be seen that rotary motion will be transmitted from thearmature to the reel and that the speed of. the latter will be greatlyreduced relativeto that of the former.

The gear chamber inside of the cylindrical part of the reel is closed atthe top by the flange 30 on the cylinder 15, and by the cover plate 31secured to the top of the reel. This chamber can be filled with oil andperfect lubrication of the relatively moving surfaces can be effected.The haulage cable 32 may be taken off from the reel 1 at any angle but Iprefer to pass it over vertical and horizontal guide rollers 33, 34 andthence to the opposite end of the locomotive where I provideguidesheaves,'35, 36, which permit said cable to be taken off for draftpurposes at a great variety of angles.

Thevmanner of using an apparatus of the kind above described will bereadily understood. The locomotive is stopped in the mine entry in suchposition that the motorman can look through the passage-way of the mouthinto the room. His assistant, the trip-rider takes the end of the cableand carries it into the room and couples it to the car to be drawn out.The motorman first by the draw-rod 23 and the rod 21 disengages theclutch-pin 18 from clutch-jaws 24 allowing the reel to freely rotate.After the end of the cable is coupled to the car the motorman can, bymeans of the rod 23 and the rod 21, thrust the clutch pin 18 intoengagement with the gear wheel 11. He then startsthe motor 8 and thereel is caused to wind up the cable and draw the car from the room tothe track in the entry. When a loaded car is sufliciently close to thelocomotive the latter is set in motion by means of its motor E and theloaded car is drawn to the point where the trains or trips of severalcars are made up.

I do not herein claim the arrangement of themotor, the reel and thecable guide devices with respect to the locomotive as a whole as thesefeatures are presented and claimed in my co-pending application forlocomotives with haulage cable mechanisms,
